Conciseness

The body is ~25 lines of pure signal: a short usage list, then four factual fields (Name, Import, Source, Description) per abstraction. Nothing explains concepts Claude already knows, no padding, every token earns its place — a direct match for the 'Lean and efficient' anchor.

Actionability

Each abstraction provides a copy-paste-ready import statement ("import { GlobalKeyValueStore } from \"webiny/api/key-value-store\"") and a concrete source path, plus the explicit instruction to read the source for exact types. It is mostly executable with a minor gap: no method signatures or usage examples, so a small trip to the source file is required — fits anchor 4, not 5, whose common cases are fully covered inline.

Workflow Clarity

The four numbered steps (find abstraction → read source → import → consult pattern skills) form a clear, coherent sequence appropriate to a simple catalog skill; nothing here is destructive or batch, so no validation checkpoint is required. Minor gaps keep it at 4 rather than 5: step 2 does not say where/how to locate the source file (the paths are repo-relative and both entries share one), and no fallback guidance is given if an abstraction is not listed.

Progressive Disclosure

The skill is under 50 lines with no need for external reference files, and it uses well-organized sections ('How to Use', 'Abstractions') with per-abstraction records — exactly the simple-skill case the guideline allows to score 5 with just well-organized structure. The pointers it does contain (source files, sibling pattern skills) are one level deep and clearly signaled.

Specificity

The description names the domain ("api/key-value-store") but the only additional content is a count ("2 abstractions") — no concrete actions or capabilities are described at all. It matches the anchor 'Names the domain but actions are minimal or generic'; not 1 because the domain is named specifically rather than being pure abstract language, and not 3 because no concrete action (catalog, list, lookup, etc.) is ever stated.

Completeness

The 'what' is only weakly implied (a count of abstractions, not what the skill does) and the 'when' is entirely absent — no 'Use when...' clause or equivalent trigger guidance. Per the judging guidelines a missing 'Use when' clause caps completeness at 3; this fits anchor 2 ('Has a vague what and no when') and not 3, which requires a clear 'what'.

Trigger Term Quality

"key-value store" is a somewhat relevant keyword, but it appears only as a technical path fragment ("api/key-value-store"), and terms like "abstractions" are pure technical jargon — no natural phrases a user would say (e.g., "key-value store", "store a value", "KV store", "webiny"). It sits between anchor 1 ('only technical jargon') and anchor 3 ('some relevant keywords but missing common variations'); noticeably below the midpoint, so 2.

Distinctiveness Conflict Risk

"api/key-value-store" carves out a clear niche within the webiny ecosystem, so it is mostly distinct with only minor overlap risk against closely related webiny api catalog skills. Not 5 because the lack of any trigger phrasing means distinguishing it from sibling skills relies entirely on the path name; not 3 because the named domain is narrow and specific rather than broad.
